INKSTAND.

Application fiIed AugustS, 1922. Serial No. 580,463.

To all whom it may concern.

Be it known that I, HARRY M. DUNGAN, a citizen of the United States of America, and a resident of Oregon, in the county of Holt and State of Missouri, have invented a new and Improved Inkstand, of which the following is a description.

My invention relates more particularly to inkstands comprising an inkwell and an inverted cup constituting a pneumatic reservoir and having an opening for the pen, preferably normally closed by a float ball valve. v

The general object of the invention is to provide an inkwell so improved that it will have a pneumatic reservoir, and be so arranged that the last drop of ink will be available for use, and that the whole inkstand can be thoroughly cleaned and washed without tools, by separating the inkstand into its simple parts, and the ink available to dip the pen into will always be of the same depth, just the depth suitable to dip the pen, and said inkstand so arranged that the evaporation will be at a minimum, either with or without an automatic closing, and to eliminate all features of waste or loss of ink.

Reference is to be had to the accompanying drawings forming a part of this specification, it being understood that the drawings are merely illustrative of examples of the invention.

Figure 1 is a vertical section of an inkstand embodying my invention;

Figure 2 is a horizontal section on the line 22, Figure 1.

Carrying out my invention in accordance with the illustrated example, a body 10 is provided having a central well or depression 11 and an annular zone 12 outside of the well, dipping in all directions toward said well; together with an inverted cup designated generally by the numeral 13, which includes a central inverted conical element 14 through which the pen nib is protruded to dip into the ink. The lower end of said central portion may normally be closed by a float ball valve 15. Outside of the conical central portion 14 is an annular depending flange 16, at the top of and outside of which is an annular flange 17 adapted to rest on the upper edge of the body 10. The flange 16'is curved vertically from its lower edge for the purpose of having only a line contact where the ink seals the reservoir, so

. that, in use, the ink dried cannot stick the ing, and without danger of breaking the inkstand itself in such process; Between the flange 16 and the central conical portion 14 is 'an annular space constituting the combined cup assemblage a pneumatic reservoir, and owing to 'thedepth of the flange to contact with the body at the base of the side walls, the said annular" space has ample content for receiving a supply of ink in filling the well. The inverted cup 13 at the flange 17 is of a less diameter than the body 10 at the upper edge so that the hands or any object cannot engage said flange to displace the cup.

In the upper edge of the body 10 at the in ner side of said edge, I may, as shown, form an oblique recess to act as a spout in pouring ink from the body 10 into the annular reservoir 18 of the cup 13 when the latter is removed and up-ended.

The contacting lower edge of the flange 16 is in the same horizontal plane as the lower end of central portion 14. The filling is effected by removing and up-ending the upper or inverted cup 13, the ink poured into it, and while in that or body is inverted and placed over the cup 13, whereupon the whole inkstand is turned right side up, the correlation of the body 10 and inverted cup 13 preventing escape or leakage of the ink, partly because of the line contact between the edge of the flange 16 with the walls of the body 10 as at A but mainly due to theitendency to outflow being opposed by the partial vacuum formed in the reservoir 18 above the ink therein when the cup '13 has been filled and then righted with the inverted body thereover, the forming of the vacuum holding the ink in the reservoir notwithstanding the bottom of the reservoir is open.

In the event that air expands at the interior of the inkstand, the inverted cup can be taken out and turned upside down and the ink from the body or lower cup can be poured with facility into the first mentioned cup by reason of the spout 19, the whole process being carried out over an old newspaper, for example, and the body now inverted and placed over the first mention cup with the ink in the latter and the complete inkstand then turned right side position the lower cup up with the previously expanded air rectifie d the operation being conducted without loss of ink.

I would state in conclusion that while the illustrated examples constitute a practical embodiment of my invention, I do not limit myself strictly to the exact details herein illustrator since, manifestly, the same can be considerably varied without departure from the spirit of the invention as defined in the appended claims.

Having thus described my invention, 1 claim:

1. An inkstand comprising a body forming a well, and a removable inverted cup fitting therein and having an inverted conical central portion open at its lower end for the entrance of a pen nib and having an annular flange outside or and spaced from said central portion, said inverted cup at the lower edge of said flange having a diameter to engage-the body at the bottom of the side walls of said body.

2. An inkstand comprising a body forming a well, and a removable inverted cup having a downwardly tapering tubular central portion open at its lower end for the entrance of a pen nib, said inverted cup having an annular flange outside of and spaced from said central portion making line contact with the body at the interior, and there being a space between the flange and body except at the contacting line.

3. An inkstand comprising a body forming a well, and a removable inverted cup fitting therein and having a central portion tapering toward its lower end and open at said end for the entrance of a pen nib, said inverted cup at the lower edge of said flange having a diameter to engage the body at the bottom of the side walls of said body, said flange being spaced from the body except at the line of contact, and said space being defined at one side by a vertically curved wall.

4. An inkwell comprising a body and a removable inverted cup therein, said body forming a well, the central portion of which is depressed, and a bottom presenting an annular Zone outside of said depressed portion and inclining in all directions to said depressed portion, said inverted cup having a central portion open at the bottom for the protrusion of a pen nib therethrough and having an annular depending flange outside of and spaced from said central portion, the lower end of said flange contacting with the body at the juncture of said annular zone with the side walls of the body, said flange above said contacting lower edge being spaced from the side walls of the body.

5. An inkwell comprising a body and a removable inverted cup fitting therein and having a form to effect a line contact only at its, lower edge with said body at the interior.

6. An inkwell comprising a body and a removable inverted cup fitting therein and having a line contact only at its lower edge with said body at the interior, said inverted cup having a chamber constituting a pneunatic reservoir for holding ink.

7. An inkstand comprising a body and an inverted cup therein having a central portion tapering toward the lower end and open at said end forming between said central portion and the outer wall or flange of the cup a reservoir adapted to hold ink and closed at all sides but the bottom, said flange of the inverted cup making a line contact with the body at the interior, permitting the filling or" the inverted cup when rip-ended and the placing of the inverted body thereover as well as the restoring of the inkstand right side up without escape of ink. I

8. An inkstand including a body and an inverted cup therein forming a reservoir into which ink may be poured when the inverted cup is removed and Lip-ended, the rip-ended inverted cup adapted to receive the body and the said inverted cup making at its lower edge a line contact only with the interior of the body.

9. An inkstand including a body and an inverted cup therein forming a pneumatic reservoir into which ink may be poured when the said cup is removed and upended, the edge of said cup making line contact only with the interior of the body.

10. An inkstand comprising a body and an inverted cup, said body forming a well and said cup when up-ended adapted to receive ink, the body furthermore having a pouring spout and said cup having a flange normally covering said spout.
